RADIATOR GP 3680803 - Caterpillar

The assembly procedure which follows is for both the left and right swing drives.1. Make sure all parts of the swing drive are thoroughly clean and free of dirt and debris prior to assembly. Check the condition of the O-ring seal used in cage (31). If the seal is damaged, use a new part for replacement. Reassemble the swing drive on Tool (A). 2. Put 5P-3413 Pipe Sealant on the inner surface of cage (31) where lip-type seal (32) fits. Install lip-type seal (32) in cage (31) with Tool (D). Install the seal with the lip facing toward the outside of the cage and until it makes contact with the counterbore in the cage. Lubricate the lip of the seal with 5P-0960 Multipurpose Grease.3. Put 5P-3931 Anti-Seize Compound on the outside diameter of bearing (30) and the inside diameter of cage (31) where bearing (30) fits. Install bearing (30) in cage (31) with a press. Install the bearing until it makes contact with the counterbore in the cage.
Do not damage lip-type seal (32) during installation of pinion shaft (28) in the cage. Also, make sure to support bearing (30) during installation of the pinion shaft in the cage.
4. Put a thin coat of 5P-0960 Multipurpose Grease on the surface of the pinion shaft that makes contact with seals (32). Install pinion shaft (28) in cage (31) and bearing (30) with a press. Install the pinion shaft until it seats against the bearing in the cage.5. Install spacer (29) over the pinion shaft.6. Install bearing (27) on pinion shaft (28) with a press. Install the bearing until it makes contact with spacer (29). 7. Make sure the mating surfaces of the cage (31) and main housing (26) are clean and free of dirt and debris. Put 1U-8846 Gasket Maker on the mating surfaces of the cage and main housing. Install the O-ring seal in cage (31). Using a press, install the cage with the pinion shaft in the main housing. Make sure the alignment marks made on the components during disassembly line up with each other. Put a thin coat of 9S-3263 Thread Lock on the threads of eight bolts (25). Install eight bolts (25) and the washers that hold the cage to the main housing.8. Adjust the end play of the coupling as follows: a. Install coupling (23) on the pinion shaft without shims (24). Install retainer (22), the locking washer and bolt (21). Tighten the bolt, but do not bend the tab on the locking washer over the head of the bolt at this time.b. Support the pinion shaft so the coupling can be moved up and down. Using a dial indicator, measure the end play of the coupling. Record this dimension.c. Add shims (24) between coupling (23) and retainer (22) until the end play of the coupling is .175 .125 mm (.007 .005 in).d. Remove bolt (21), the locking washer, retainer (22) and coupling (23) from the pinion shaft. 9. If the two
